  Have you tried lowering the 802.11 transmission retry count to 0?

  In 802.11, a transmitter has to receive acknowledgement of the last
  packet it sent in about 10 microseconds, or else it will retransmit
  it. An 802.11 radio is typically set to retransmit about 5 times before
  it gives up.

  On a 10 mile link, the roundtrip time is about 100 microseconds,
  so ACKs are coming 90 microseconds too late. Every packet may be
  retransmitted 5 times, which really cuts into your available bandwidth.
  It may also play havoc with TCP, cutting the bandwidth even more.
